Pico Executive HD

Pico Executive HD: Concentrated state of the art

Model Comparison Chart >


Performance details

Application(s). Time-coherent 3-way speakers sounds best on the floor, a credenza, or bookshelf.

User adjustability (Soundfield Convergence™). Midrange and tweeter adjust front-to-rear independently and together as one unit.

Room size. Small to medium, 150-600sf.

Power (amplifier’s 8 ohm rating). 7 to 170 Watts.

Response. In-room, typically +/- 2dB from 50Hz to 20kHz; -3dB frequencies below 45Hz and above 24kHz.

Distortion. <0.5% harmonic 100Hz-12kHz, <1% intermodulation, both at 98dB at 1m. (I.M.D. is for any two frequencies separated by a 10:1 ratio.)

Phase shift. +/- 2 degrees acoustically, from 220Hz to 8kHz. Does not vary with loudness.

Rise time. <10 microseconds, positive or negative input. Does not vary with loudness.

Polarity. Positive, over full bandwidth.

Dispersion. Omni at 45Hz, smoothly decreasing to cardioid at 10kHz.

Impedance. 5.25 Ohms, +/- 0.75 Ohms 150Hz to 20kHz. Does not vary with loudness.

Sensitivity. 90dB for 2.83V at 1m, at sea level. Dynamically linear within 0.5dB to 100dB.

Max SPL. 105dB peak at 3m from stereo pair, first-arrival (without room gain).

Pair matching. Amplitude +/- 0.25dB; impedance +/- 0.15 Ohms, 160Hz-8kHz; crossover parts +/- .15%.


Physical details

Cabinet finish and choices. Clad in black Texture-Kote™ for the look of pin-grained leather. Standard side panels in softly-padded black leather; choose another leather color or send four 12x12" stone or marble tiles for installation at no additional charge (contact us first for details).

Speaker Conditioning. Upon request, we will gladly condition the speakers' drivers before shipment at no additional charge.

Bi-Wire. If you insist, the Pico Executive HD may be bi-wired for USD$900. If you do not already own two sets of high-quality speaker wires, we prefer that you do not order this option and instead, invest in one set of superior wires.

Upgrades. Not available for Pico Executive to Pico Executive HD status.

Grilles. Speakers have been designed for woofer grilles to be left in place. There are no upper grilles.

Accessories in the box. EarStick; nut driver; T-handle Allen wrench; adjustable cone feet with hardwood floor protectors; brush for dusting tweeter and midrange drivers; bottle of leather polish and Ownership Guide.

Size. 30.625"H; 10.5"W; 12.75"D.

Weight. 45lbs. (20.5kg) each.

Technical specifications

Woofer

Woofer diameter. 6" (17cm).

Woofer construction. Single-pressed paper/carbon fiber cone with ultra-linear suspension, vented under-hung 2-layer, 1" (25mm) voice coil wound on Kapton former. Mechanically damped chassis. Shielded, radially-magnetized, neodymium-iron-boron magnet structure with heat dissipating black coating; 0.32" (8mm) p-p linear excursion; 9.85g moving mass.

Woofer cabinet. Woofer mounted in 2-layer wood cabinet of 13-layer Baltic Birch plywood and MDF. 4th-order Butterworth ported.

Woofer / Bass port. 3" (7.5cm) aerodynamic top port tuned to 54Hz. The Pico Executive HD’s port is large for its woofer size. Its top location keeps it close to the floor while allowing bass pressures to fully expand into the room. All this produces maximum bass from a small enclosure.

Midrange

Midrange diameter. 5.25" (13cm).

Midrange construction. Ultra-low-mass rigid cone of graphite and wood fiber. 3.13g moving mass. Low resonant frequency from high-compliance suspension. Coated multi-fold cloth surround and large spider. 1" (25mm) voice coil, alloy phase plug. Alloy chassis; 20oz. magnet. 0.25" (6mm) p-p linear excursion. Response -3dB at 350Hz and 3,150Hz.

Midrange enclosure. Resistively vented in alliptic, non-diffractive Q-Stone™ enclosure containing damped acoustic line. The resistive vent suppresses the natural low-frequency resonance.

Tweeter

Tweeter diameter. 1" (25mm).

Tweeter construction. Lightweight, treated-fabric dome. High-compliance polymer suspension. Ferrofluid cooled voice coil with highly-flexible lead-in wires. Fully vented into large, damped alloy rear chamber. 0.35g moving mass. Six radially-magnetized neodymium magnets.

Tweeter enclosure. In non-defractive, Q-Stone™ enclosure with integrated tweeter chassis damping.

CopperMatrix

Wiring. Woofer, Midrange, Tweeter: Exclusive High Definition CopperMatrix™ wire by Marigo Labs: 18-gauge, 500+ strand Litz wires of six-nines purity, single crystal, oxygen-free copper with proprietary winding geometry; double cryogenically-treated, organic dielectric insulation; proprietary internal vibration damping system. Pure metals love to ring. They do so sideways and also along their lengths. Because of their design, these CopperMatrix™ wires do not and can not ring.

Binding-posts

Crossover. Balanced-Phase™ first-order circuit.

Zobel circuit's capacitor. Woofer, Midrange, Tweeter: Ultra-premium quality.

Crossover principal capacitor. Woofer: N/A. Midrange, Tweeter: Ultra-premium quality.

Crossover bypass capacitor. Woofer: N/A. Midrange, Tweeter: Ultra-premium quality.

Binding posts. Made by Vampire Wire of pure oxygen-free copper, directly gold plated. Mounted on the back.
